摘    要:高速摄影是研究焊接物理的一种有效的测试技术 ,但目前没有解决多路信号与高速摄影胶片同步对应的问题。利用快速多路计算机数据采集系统配合相应传感器同时采集多路信息 ,利用高速摄影胶片记录电弧图像变化过程 ,设计专有的同步标度信号脉冲作为计算机多路信息与高速摄影胶片之间的同步媒介 ,成功地实现了多信息同步高速摄影。文中详细介绍了多信息同步高速摄影的原理、同步标度信号脉冲产生方式及其接口技术 ,并利用该装置成功地进行了光谱信息对熔化极气体保护焊熔滴过渡过程检测的验证。实践证明 ,多信息同步高速摄影是行之有效的 ,给焊接电弧过程的进一步研究提供了有力的试验手段

关 键 词:高速摄影  同步  多信息  焊接

Abstract:High speed photography is an effective testing instrument in welding arc physics research work,but current high speed photography has not solved the problem of multi signal waveforms synchronizing to photograph pictures.This paper has designed a high speed photography with multi information synch.Its data are sampled by using a fast data sample card of computer and corresponding sensors and its pictures are taken by using high speed photography.A synch time mark is used as medium between photographs and signal waveforms.The principles of the device of the synch time mark maker and its interface to computer have been presented in detail in this paper.With the synchronizer this paper succeeds in validating the spectrum sensing of droplet transfer.Experiment results show that this synchronizer is an effective device,which would provide favorable means for welding arc physics research work.
Keywords:high  speed photography  synchronizer  multi  information  welding
